Damage Detection in Plates with the Use of Laser-Measured Mode Shapes

Figure 8

Results of damage detection for the first three modes: (a) MF method, (b) LMF method, and (c) WV method. Coloring of areas refers to damage scenarios under investigation, with temperature rise marked in grey and damage cases 1 and 2 marked with light and dark light red and yellow, respectively. Values are normalized so each time maximum indication of the given method would equal 1.
